, and in Great Britain November 15 1928 Claims. (01. 131-39) This invention relates to cigarette making machines of the continuous rod type wherein tobacco is fed from a hopper into a trough having a travelling band or web of cigarette paper ar- 5 ranged to move relatively thereto, and has for its object the provision of means for improving the consistency of the cigarette rod produced upon such machines running at high speeds.

In cigarette making machines of the above type, the tobacco is showered vertically into the trough of the machine, and it will be understood that where the same meets a web of paper running at a high speed there is a tendency for variations to occur in the density of the rod, due to the vertically falling tobacco suddenly assuming a horizontal movement.

The present invention consists of a cigarette making machine of the continuous rod type wherein the tobacco showered into the trough of the machine is given a movement in the direction of movement of the cigarette rod, prior to the same engaging with the said band or web of cigarette paper.

The invention will be more particularly described with reference to the accompanying drawings, in which:-

Fig. 1 shows a section of a tobacco hopper constructed according to the invention.

Fig. 2 is a front elevation of Fig. 1 showing the feeding rollers, and

Figs. 3 and 4 show modified forms of the invention.

Referring to Fig. l, the tobacco is placed in the hopper 1 and fed by a roller 2 to a combing roller 3 from which it is picked by a picker 4 after passing beneath the brushing roller 5, and showered on to a distributing roller 6.

The carded tobacco is picked from the distributor 6 by a further picker roller 7 and showered on to a web of cigarette paper arranged to travel in the trough 9.

A guide plate 10, which receives the tobacco from the picker roller 7 is provided with a series of inclined vanes 11 as shown in Figs. 1 and 2, so that when the falling tobacco strikes the vanes 11 the same is given a movement in the direction of movement of the travelling web of cigarette paper 12 which is automatically drawn through the trough 9.

As shown in Fig. 2, the vanes 11 are curved somewhat at their lower extremity, and this curve and the angle of the vanes may be varied to suit requirements so that the tobacco approaches the paper in a direction as nearly as possible tangential.

By applying the vanes 11 to the plate 10 at a suitable. upstanding angle relatively to the plate, it will be understood-that the shredsof tobacco will fall in the angle formed by the vanes of the plate, thushaving the tendency to alignthe shreds of tobacco and influence the same to be located in the direction in which the tobacco is travelling. r

If desired, I may form similar vanes in the opposite plate 13 so as to ensure that none of the falling tobacco can escape from being directed into the slanting direction above explained. Referring to Fig. 3, it will be seen that the distributor drum 6 is placed at an angle to the chute 10 and receives tobacco from the carded roller 3 in the usual way. The last picker 7 is placed parallel to the distributor, and consequently, the falling tobacco receives a movement in the direction of the moving web of paper.

If desired, the drum 6 may be replaced by a belt in any of the forms of the invention described or illustrated.

In the modified form shown inFig. 4, the last picker roller 7 is placed at an angle with respect to the distributor 6. The picker 7 is of a concave formation in order that it may mate with the distributor 6, or'if desired the picker pins may be longer at the extremities of the drum to produce the same effect.

What I- claim as my invention and desired to secure by Letters Patent is:

1. In apparatus for use in a cigarette making machine, the combination with means for supporting a travelling web for movement in a predetermined path, of means for discharging loose tobacco upon said web in a direction having a component in the direction of movement of the web, said last named means includingplurality of stationary elements spaced longitudinally of the web, said elements being interposed in the path of the discharging tobacco and inclined downwardly and forwardly in the direction of movement of the web.

2. In apparatus for use in a cigarette making machine, the combination with means for supporting a travelling Web for movement in a predetermined path,'of means for discharging loose tobacco upon said web in a direction having a component in the direction of movement of the web, said last named means including guide plates on either side of and above said moving web for preventing lateral discharge of the tobacco,-

and a plurality of stationary plates located intermediate said guide plates and spaced longitudinally of the web, said plates being interposed 2 in the path of the discharging tobacco and inclined downwardly and forwardly in the direction of movement of the web.

3. In apparatus for use in cigarette making machines, the combination with means for supporting a travelling web for movement in a predetermined path, of means for simultaneously discharging loose tobacco in a shower upon said web at a plurality of points distributed along a substantial portion of the length of the web and in a direction having a component in the direction of movement of the'web at the instant of engagement of the tobacco with the web, said means including a plurality of stationary ele ments spaced longitudinally of the web, said elements being interposed in the path of the discharging tobacco and inclined downwardly and forwardly in the direction of movement of the web.

4. In apparatus for use in cigarette making machines, the combination with means for supporting a travelling web for movement in a predetermined path, of means for showering loose particles of tobacco upon the web in an elongated sheet extending longitudinally of the web with the particles forming the sheet impinging on the web in a direction having a substantial component in the direction of movement of the web, said means including a plurality of stationary guide plates spaced longitudinally of the web and extending into the tobacco sheet, said plates being inclined downwardly and forwardly in the direction of movement of the web.

5. In apparatus for use in cigarette making machines, the combination with means for supporting a travelling web for movement in a predetermined path, of means including a feed roller adjacent the web and having the axis thereof disposed in a vertical plane lying substantially parallel to the path of movement of the web for simultaneously discharging loose tobacco in a shower upon said web at a plurality of points distributed along a substantial portion of the length of the web, stationary means interposed between said feed roller and said web for imparting to the discharged tobacco a movement in a directionvhaving a component in the direction of movement of the web at the instant of engagement of the tobacco with the web.
